8-bit (and therefore 24-bit which is nothing but 3x 8-bit) is not deep color. 10-bit and 12-bit (30-bit / 36-bit) are called deep color.

There are no commercial media available in deep color. Blu-Ray media is currently encoded at 8-bit only.

Some Blu-Ray players offer color-interpolation (e.g. Sony's superbitmapping). Video processors can also offer internal 10-bit processing, so if you have a deep color connection, enabling deep color on both the VP's output and the display's or beamer's input helps to avoid another downconversion to 8-bit.

4:2:2 / 4:4:4 has nothing to do with the color depth, but it's the actual pixel resolution. 4:4:4 means full resolution for the luma channel (Y) and both color channels, while 4:2:2 is a full resolution luma channel and color channels at half resolution.

Your beamer (and actually most modern displays) will allow you to feed 10-bit deep color in 4:2:2 resolution, while 4:4:4 is only supported at 8-bit color depth.

Thanks for quick reply. Now I understood it better. The question I have how is it possible to use equal 3x8 bit(y, cb,cr) for 3 channels with unequal resolution 4:2:2.

why not ? the bit-deph just says how many different "shades of colors" are available for a single pixel in the image (in the particular channel). It doesn't matter if the resolution is 480p, 720p, 1080i or 1080p or if one of the channels has a higher resolution than the others.

Thanks for reply. You are referring 4:2:2 or 4:4:4 as resolution and different shades of color (cb,cr) and luma(y) as color depth. Is it right?

I also read little more on 4:2:2 and this is what my understanding. If image is sampled for 4x4 pixels and sampled at resolution of 4:2:2, then there are 4x4 y channels and 4x2 channels for each cb, cr. Am I right?

Assuming that each channel (y,cb,cr)may need 8 for basic or more than 8 for deep color. I want to make sure that if 4x4 image is stored in

1. 4:2:2 at 10 bit deep color. The number of bits are
4x4x10 = y (first number tells number of rows, second number how many pixels are used in each row)
+
4x2x10 =cb
+
4x2x10 = cr

If you take the Y channel on it's own, then the "4" doesn't mean anything. Y is always full resolution (e.g. 1920x1080p). The 4 only makes sense in comparison to the other channels, where 4:2 means that the Cb channel has HALF the resolution of the Y channel.
